That is a good point.. these are just my conceptual thoughts (at this stage without any real experiments to back up my claims). The thing with nested hierarchies is exactly at the core of my question. If some lower layers are not hierarchies in sense of local interaction, we might not be able to simulate them on layers that "understand" only hierarchical structures. (for instance the main strategy for humans to deal with complexity is by decomposition into nested hierarchies)
